President Trump drew an estimated 16,000 people to his rally in El Paso on Monday - claiming victory in his battle with Democratic upstart Beto O'Rourke.

Trump, who chose the border town as the venue for a rally to drum up support for his promised wall along the frontier with Mexico, spoke at the El Paso County Coliseum on Monday.

O'Rourke held his counter-rally a few hundred yards away at Chalio Acosta Sports Center.

An unofficial estimate of Trump’s crowd size puts the number at 6,500 inside the arena and between 10,000-12,000 outside, according to MSNBC.

As for O’Rourke’s rally, MSNBC reported that an estimated 7,000 people attended, while Bloomberg News reported that El Paso police estimated a crowd of between 10,000 and 15,000.

‘Not too good. In fact what I would do, that may be the end of his presidential bid.’

Trump later claimed that although the coliseum holds a capacity of 6,500, the local fire department gave him special permission to allow 10,000 inside.

But the El Paso Fire Department said this was incorrect, according to the El Paso Times.

The department said that while the coliseum was at full capacity, thousands more watched outside on a large screen.

In total, there may have been 10,000 people, according to Enrique Aguilar, the fire public information officer.

O’Rourke, whose unexpectedly close but ultimately unsuccessful campaign for U.S. Senate generated buzz about a 2020 presidential bid, said last week he will decide by the end of the month whether to run.

In a taped interview with Oprah Winfrey in New York, O’Rourke, 46, appeared to be leaning toward a 2020 campaign for the White House but said he would make his decision after consulting his wife and three children.

'I have been thinking about running for president,' he said, prompting wild applause.
